Preheat a grill to 500 to 550 degrees. Rub steaks with oil and season liberally with salt and pepper. In a bowl, combine vinegar, butter, shallots, and garlic. Transfer steaks to grill and using the herb bundle, brush steaks with basting mixture. Flip every minute for 4 minutes, basting each time. Then, flip and baste every 2 minutes until the steaks reach 120 degrees. Let rest for 5 to 10 minutes before carving and serving.
